#1 [19.6] Bifunctional DNA multivalent structure integrating stable capture of urothelial carcinoma cells with CRISPR/Cas12a signal amplification for bladder cancer detection.

Noninvasive detection of bladder cancer remains challenging due to the limited analytical performance of current urine-based assays under realistic detection conditions. Here, we report a linear programmable DNA nanostructure that integrates multivalent aptamer recognition with CRISPR/Cas12a signal transduction for detecting tumor-derived urinar...

#2 [16.1] Integrated single-tube detection of miRNAs in subpopulation-specific extracellular vesicles via spatially colocalized dual-module DNA scaffold.

Extracellular vesicles (EVs)-derived miRNAs are valuable non-invasive biomarkers for early cancer diagnosis. However, most current methods detect either total EVs-miRNAs or those from a single subpopulation, overlooking subpopulation heterogeneity. Moreover, EVs isolation and miRNA analysis are often conducted in separate workflows, increasing s...

#3 [14.7] A Cascaded DNA Nanocircuit for Multi‐Signal‐Responsive Precision siRNA Delivery in Cancer Therapy

Precision control over nucleic acid delivery remains a critical challenge in cancer therapy, particularly for siRNA-based gene silencing, where off-target effects limit clinical translation. Herein, we report a programmably engineered DNA nanocircuit with cascaded dual-AND logic gates, which enables the development of a spatiotemporally controll...

#4 [13.6] Antibodies and aptamers as affinity ligands for exosome isolation, detection, and targeted delivery: A review.

Exosomes, key mediators of intercellular communication, are emerging as promising tools for disease diagnosis and therapy. Realizing this potential depends on technologies that can isolate, detect, and deliver exosomes with high specificity and efficiency. Affinity-based strategies that exploit the molecular recognition of antibodies and aptamer...

#5 [13.5] Enzyme-free dual-hotspot SERS immunosensor via cascaded boronate assembly

The precise detection of CA19-9 is paramount for early cancer diagnosis and clinical monitoring. However, traditional immunoassays are often hampered by their heavy reliance on matched antibody pairs and the insufficient sensitivity of enzymatic amplification systems. To address these limitations, we report a novel, enzyme-free surface-enhanced ...

#6 [13.0] Targeting Adaptive and Innate Immune Responses with Covalent Aptamers.

Covalent aptamers have recently found initial success as tools for fast and selective transfer of labels to target proteins. Here, aptamers targeting protein tyrosine kinase 7 (PTK7) and the mesenchymal-epithelial transition factor (cMet) were functionalized with electrophiles capable of covalently transferring small-molecule immune recruiters. ...

#7 [12.8] A bioelectronic interface for continuous neuroinflammation monitoring and neuromodulation in Parkinson's disease model.

Neuroinflammation is increasingly recognized as a critical driver in the onset and progression of Parkinson's disease (PD), yet technologies capable of continuously tracking neuroinflammatory dynamics in vivo remain limited. Here, we report an implantable bioelectronic interface that integrates multiplexed aptamer based electrochemical biosensin...

#8 [12.4] A type of magnetically induced self-assembled electrochemical aptamer nanobiosensor for ultrasensitive detection of hypoxia-inducible factor 1α protein

Background Hypoxia-inducible factor 1α (HIF-1α) protein has been identified as an aggressive malignant phenotype marker for numerous tumors; therefore, the detection of HIF-1α has become increasingly significant. Methods In this work, we developed a type of magnetically induced self-assembled electrochemical aptamer nanobiosensor for detecting H...

#9 [12.2] Potentiating In Vivo Precision Cancer Therapy With Modularized Aptamer-Chemotherapeutics Conjugates Based on DNA Tiling-Mediated Structural Nanotechnology.

While DNA origami nanotubes have been often used in the biomedical field, the technical challenges in the assembly at large scale and the susceptibility to degradation limit their exploration for clinical application. In the current contribution, we propose a structural DNA nanotechnology (TMM) for the construction of a degradation-resistant DNA...

#10 [12.0] Catalytic BiFeO3/g-C3N4 Heterojunction Nanosheets Coupled with DNAzyme/Low-Leakage Sequential DNA Circuit for Ultrasensitive Electrochemical Aptamer-Based Detection of Colorectal Cancer Exosomes

Abstract Tumor-derived exosomes are promising circulating biomarkers for early colorectal cancer (CRC) diagnosis, yet their low abundance and the complexity of biological fluids demand sensing strategies with both stringent specificity and amplified signal output. Here, we report an ultrasensitive electrochemical aptasensor for SW620 cell-derive...
